Error during installation

[armin-gh]

VM on Proxmox with Debian Bookworm
the Python 3.12 backport from https://github.com/pascallj/python3.12-backport was installed

After adding the Python3.13 backport to source.list.d and running "apt install" hit the following error:

Unpacking python3.13 (3.13.2-1~bpo12+1) ...
dpkg: error processing archive /var/cache/apt/archives/python3.13_3.13.2-1~bpo12+1_amd64.deb (--unpack):
 trying to overwrite '/usr/local/bin/pip3', which is also in package python3.12 3.12.8-3~bpo12+1
Errors were encountered while processing:
 /var/cache/apt/archives/python3.13_3.13.2-1~bpo12+1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Workaround to force installation:
apt --fix-broken install -o DPkg::options::="--force-overwrite"

I will look into this when I get home. It occurs because of a workaround I had to implement with an incompatible pip version in Debian with Python 3.12 or later.

If you don't need Python 3.12 from my other backport, it is better to uninstall that first. That should prevent the error.

Thank you for reporting this! It should be fixed when the new builds succeed and are uploaded to the repository. This issue also fixes the same error when the system-wide python3-pip was installed. However apparently this wasn't common, because this bug was already present in the Python 3.12 backport and then no one reported this.

Already existing virtual environments should be unaffected.
